After the therapy session I had context. What I did not have was data.

The agents knew who I was. They did not know anything about my work. Ask a specific question and they had nothing to draw on. The intelligence was not in the system. It was still in my head.

I needed somewhere to store information so the agents could use it. Something with an API. Something cheap. Something I could start building with quickly.

Claude suggested Notion. I was already using it loosely. It had an API. It looked like a database. It was already open on my screen.

So I used it.

It worked, in the way that first attempts work. The agents came back with more relevant answers. There was progress. For a while it felt like the right call.

The problem was not Notion itself. The problem was what the system became.

I was only putting part of the information in. So the agents could only give me part of the answer. Every question I asked, I had already answered in my head. The agents were confirming what I already knew, not surfacing what I did not.

That is a data problem, not an AI problem.

The deeper issue took longer to see. As the system grew, the cracks in using Notion as a machine backend became obvious. It is built for humans to read and edit. It is not built for multiple automated processes hammering its API simultaneously. It has rate limits. It has no real query language. Every relational lookup that takes one line in a proper database takes several API calls and manual joins in Notion.

The moment I understood the mistake properly was when I read a note in my own build documentation. Written by me, about the system I had built:

"Notion has zero human consumers. It was set up for the agent."

That is the architectural error in one sentence. I had taken a tool designed for people and turned it into a machine database. Nobody was opening Notion to read anything. The agents were writing to it. The agents were reading from it. And the tool was never built for that.

The choice made sense when I made it. It stopped making sense as soon as the system became real.
